Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((Benzylthio)methyl)-6,8-dichloro-3-(2,6-dimethylphenyl)quinazolin-4(3H)-one.
2-((Benzylthio)methyl)-6,8-dichloro-3-(2,6-dimethylphenyl)quinazolin-4(3H)-one (CAS 338957-47-4) is a high-purity analytical reference standard with the molecular formula C24H20Cl2N2OS and a molecular weight of 455.40 g/mol.
2-((Benzylthio)methyl)-6,8-dichloro-3-(2,6-dimethylphenyl)quinazolin-4(3H)-one (C24H20Cl2N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
